Battery clock

Claim 2

A battery-operated clock comprising: a. a clock housing; b. a chamber for receiving a battery formed within said housing; c. an opening formed in said housing for inserting a battery into said chamber; d. a moveable electrical contact plate; e. a first fixed electrically conductive plate; f. said moveable electrical contact plate being mounted adjacent said opening for sliding movement across said opening and along said first fixed electrically conductive plate and being operable to cover said opening; g. said moveable electrical contact plate being resiliently urged against said first fixed electrically conductive plate; h. said first fixed electrically conductive plate being in electrical connection with an electric consumer within said housing; and i. means for preventing the removal of said contact plate through said opening.

Claim 3

A clock according to claim 1 wherein: a. said moveable electrical contact plate is concaved in configuration; b. said first fixed electrically conductive plate is generally flat in configuration; and c. a holding element attaches said moveable electrical contact plate to said first fixed electrically conductive plate whereby said moveable plate is biased against said fixed plate.

Claim 4

A clock according to claim 1 wherein said first fixed electrically conductive plate is formed with at least one resilient electrical contact tongue which is urged against a first current supply contact of said electric consumer.

Claim 5

A clock according to claim 1 wherein said opening for inserting said battery is formed on a bottom side of said clock housing.

Claim 6

A clock according to claim 2 wherein: a. One end of said holding element protrudes through said housing; and b. said holding element is adjustable whereby said moveable electrical contact plate may be positioned over said opening from outside said clock housing.

Claim 7

A clock according to claim 3 with the addition of: a. a second fixed electrically conductive plate; b. said second plate being disposed within said housing at an end thereof away from said opening; c. said second plate being formed with two electrical contact arms; and d. one of said electrical contact arms of said second plate comprising said counter contact urging resiliently against said battery and the second of said electrical contact arms comprising a second electrical connection for said electric consumer.

Claim 8

A clock according to claim 3 wherein: a. said electric consumer comprises printed circuit means; and b. each said at least one resilient electrical contact tongue of said first fixed electrically conductive plate urges against a conductive portion of said printed circuit means.

Claim 9

A battery-operated clock comprising: a. a clock housing; b. a chamber for receiving a battery formed within said housing; c. an opening formed in said housing for inserting a battery into such chamber; d. a moveable electrical contact plate; e. a first fixed electrically conductive plate; f. said movable electrical contact plate being slidably mounted on said first fixed electrically conductive plate and being operable to cover said opening; g. said movable electrical contact plate being urged against said first fixed electrically conductive plate; h. said first fixed electrically conductive plate being in electrical connection with an electric consumer within said housing; i. said contact plate being formed with a beveled surface comprising a portion of a first end of said contact plate; j. said first end of said contact plate being the end of said contact plate operable to cover said opening upon the movement of said contact plate to a position over said opening; k. a counter contact pRovided within said housing and disposed adjacent to an end of a properly inserted battery which end is away from said contact plate; l. said beveled surface being operable to urge the battery against said counter contact in response to the movement of said contact plate to a position covering said opening; and, m. a contact element provided on said contact plate adjacent said beveled surface, said contact element being operable to engage a pole of said battery.

Claim 10

A battery-operated clock comprising: a. a clock housing; b. a chamber for receiving a battery formed within said housing; c. an opening formed in said housing for inserting a battery into such chamber; d. a moveable electrical contact plate; e. a first fixed electrically conductive plate; f. said movable electrical contact plate being slidably mounted on said first fixed electrically conductive plate and being operable to cover said opening; g. said movable electrical contact plate being urged against said first fixed electrically conductive plate; h. said first fixed electrically conductive plate being in electrical connection with an electric consumer within said housing; i. said contact plate being formed with a beveled surface comprising a portion of a first end of said contact plate; j. said first end of said contact plate being the end of said contact plate operable to cover said opening upon the movement of said contact plate to a position over said opening; k. a counter contact pRovided within said housing and disposed adjacent to an end of a properly inserted battery which end is away from said contact plate; l. said beveled surface being operable to urge the battery against said counter contact in response to the movement of said contact plate to a position covering said opening; and, m. a contact element provided on said contact plate adjacent said beveled surface, said contact element being operable to engage a pole of said battery.

Claim 11

A clock according to claim 1 wherein said contact element comprises an indentation formed on said contact plate for receiving a protruding pole of said battery.
